Lost IMEI need help

Dear Friend,
anyone of you have G-PRO especially those with non-international version should backup your IMEI before trying to upload any new ROM. To back up, please download the tool below (I took it from M_Tool of someone I don't remember) and run it from a CMD Administrator windowl; you should also have your phone connected with debug mode, rooted phone and adb.exe shall be in PATH.
I bricked up my phone with losing the IMEI, i could restore partly now but could not connect to 3G network (only GSM). The reason was that my back up lacking of some files. So anyone have G-PRO F240L or a 988 please be so kind to give me a version of your backup. I need that to make my phone back to a smartphone.
Regards,
Quang

Have you tried taking your phone to a service shop? I believe that would be your best shot. They might restore it in a matter of minutes...
You might have better luck choosing an independent store rather than a licensed one.

some times its a imei issue. in my case it was sim tray issue. i had to change the sim tray from service center only.
have you taken backup before flashing new rom?
if yes, then restore the EFS folder from CWM or TWRP backup

If you have restored the backup properly, just try to factory reset the firmware...
Which method you had used to backup and restore EFS?

I did not have EFS backup so I used SRS unlock client with UART cable to bring back the original IMEI, now my IMEI and S/N is correct but phone still wont register on network. Any ideas?

I am having the same issue after having flashed the 4.3 version found on Sammobile. SN and IMEI are correct. Have you found a solution?

Please help me too , same situation
previously worked with dlk6 or dll6 firmware/modem on 4.1.2
When I flashed 4.3 Xperia-z1-ized ROM . Device showed correct imei and MK1 modem from the ROM but says "not registered in network "
Have no Idea what went wrong. I have no backup of any EFS or anything .
I installed emergency firmware upgrade via Kies and now running stock 4.3 Android UBUEMJ4 Modem , build number : MK4 Status : offical.
I don't even know if i can root my device with current stock firmware.

Professional Help and advise needet.

Hello to everybody,
First of all sorry for my english.
So about what is the tread
There is arround 10 bricked phones in Bulgarian Android Forum.Becouse we cant find where is the problem I decide to ask here.
Problem: After flashing stock test 4.3 and downgrade after back to 4.1.2 the result is --IMEI 0049 and Permanent Test Mode.
what we know until now:
Phones bought from shops for phones reported they downgrade back without issues
Phones bought from mobile operators -bricked IMEI
Flashing again 4.3 after brick do not restore IMEI
P.s
Sorry if the tread is on wrong place and 10x for your opinions about problem

Impact on device/How I know I have corrupted EFS
When there is EFS partition is corrupted, device loses IMEI and due to this device can't gets connected to network. Baseband info also sometimes shows unknown.
-Check your IMEI in setting / by dialling *#06# if it is null OR if it starts with 0049** then IMEI is generic and corrupted. In Normal case IMEI which you can see in device setting or dialing *#06# is exactly same you can see on bill/box/sticker under battery compartment
-If you are unable to connect to network in spite of correct IMEI, chance are
A. Your device is Locked to specific Network OR
B. Your device is banned due to tempered IMEI
-If your AP,CP,CSC all are correct and even you are getting error (unknown CSC XXX) on kies update, it may be due to corrupt Product code in EFS. Read This for detail.

If you dont have efs backup then you probably need the z3x box to make repair for your imei and change it to the original one didnt test the ariza patch on this kind of problem but why not give it a shot
